# NodeList

`public interface NodeList`
``

org.w3c.dom.NodeList

The `NodeList` interface provides the abstraction of an ordered collection of nodes, without defining or constraining how this collection is implemented. `NodeList` objects in the DOM are live.

The items in the `NodeList` are accessible via an integral index, starting from 0.

See also the Document Object Model (DOM) Level 3 Core Specification.

## Summary

### Public methods
`abstract int` | `getLength()` The number of nodes in the list.
`abstract Node` | `item(int index)` Returns the `index`th item in the collection.

## Public methods

### getLength

    public abstract int getLength ()

The number of nodes in the list. The range of valid child node indices is 0 to `length-1` inclusive.

Returns
`int` |

### item

    public abstract Node item (int index)

Returns the `index`th item in the collection. If `index` is greater than or equal to the number of nodes in the list, this returns `null`.

Parameters
`index` | `int`: Index into the collection.

Returns
`Node` | The node at the `index`th position in the `NodeList`, or `null` if that is not a valid index.
